What the father obviously means is:

"My horny teenagers were reading lesbian porn and when I caught them, they made up a stupid lie about military academics because lesbians = bad. In the following nights I was constantly disturbed by both the sounds that came from their room and my own thoughts about hot lesbian sex. I don't want to admit either of those facts, so following the great example of my sons, I lie about everyhing in order to get money out of it."

That being said, damn that's amusing.
